摘要
介绍了变压吸附法的原理及工艺过程,讨论了吸附剂的选择、主要操作条件的影响,并进行了社会、经济和环境效益分析。分析表明,变压吸附法是目前最具有发展前景的瓦斯富集分离技术,炭材料由于吸附非极性分子甲烷时受水的影响较小而在天然气浓缩研究中被广泛用作吸附剂;半周期、均压流程、吸附压力和解吸压力是影响双塔真空变压吸附分离效果的主要操作条件。
In this paper, the principle and technological process of the pressure swing adsorption method were described, the selection of the adsorbent and the effect of the main operating conditions were discussed, and the social, economic and environmental benefits were analyzed. The analysis results showed that pressure swing adsorption method was the most promising technology for concentrating and separating mine ventilation air methane, the carbon materials were widely used as adsorbents in the study of the natural gas concentrations due to less influence by water while absorbing non-polar molecules methane ; the half- period, the flow of pressure balance, the adsorption pressure and desorption pressure were the main operating conditions that affect on the vacuum pressure swing adsorption separation of the double-tower.
